Airbus has to use the A350-1000 toolbox to design something similar. The aircraft would be shorter than a -1000, however, to optimize its efficiency. How much better in efficiency than the 777F would it be? We put both in our performance model and fly them from China to the US.
An Airbus A350 freighter has to come close to the 104t payload of the 777F.
Can it do that, it has convincing economics compared with the 777F.
